BACKGROUND OF THE PRESENT INVENTION Field of the Present Invention

The present invention relates generally to the field of racks, framesand cabinets for mounting and storing electronic components, and, moreparticularly, to reduced-complexity structures with high strength andcapacity.

Background

Racks, frames and cabinets for mounting and storing electroniccomponents have been well known for many years. Frames and racks aretypically simple rectangular frameworks on which electronic componentsmay be mounted, or on which other mounting members, such as shelves orbrackets, may be mounted which in turn may support the electroniccomponents. Cabinets are typically frames on which panels or doors, orboth, are hung to provide aesthetic improvement, to protect thecomponents from external influences, to provide security for thecomponents stored inside, or for other reasons. Racks, frames andcabinets (sometimes collectively referred to hereinafter as“enclosures”) have been built in many different sizes and with manydifferent proportions in order to best accommodate the components whichthey are designed to store.

Various aspects of these enclosures have increased part counts andweight and created additional cost and manufacturing complications. Inone example, cable management accessories and equipment are mounted inan enclosure on a bracket that is attached to a vertically-orientedequipment mounting rail. Because the bracket is a separate structuralcomponent from the vertical mounting rail, these structures occupygreater space within the enclosure. Additionally, such structurestypically result in greater cost due to the extra materials and hardwarecomponents necessary to install the separate bracket.

Accordingly, a need exists for improved design and manufacturability inracks, frames and cabinets in order to enhance the utilization of spacewithin an enclosure and reduce manufacturing and assembly costs.

DETAILED DESCRIPTION

As a preliminary matter, it will readily be understood by one havingordinary skill in the relevant art (“Ordinary Artisan”) that the presentinvention has broad utility and application. Furthermore, any embodimentdiscussed and identified as being “preferred” is considered to be partof a best mode contemplated for carrying out the present invention.Other embodiments also may be discussed for additional illustrativepurposes in providing a full and enabling disclosure of the presentinvention. As should be understood, any embodiment may incorporate onlyone or a plurality of the above-disclosed aspects of the invention andmay further incorporate only one or a plurality of the above-disclosedfeatures. Moreover, many embodiments, such as adaptations, variations,modifications, and equivalent arrangements, will be implicitly disclosedby the embodiments described herein and fall within the scope of thepresent invention.

Accordingly, while the present invention is described herein in detailin relation to one or more embodiments, it is to be understood that thisdisclosure is illustrative and exemplary of the present invention, andis made merely for the purposes of providing a full and enablingdisclosure of the present invention. The detailed disclosure herein ofone or more embodiments is not intended, nor is to be construed, tolimit the scope of patent protection afforded the present invention,which scope is to be defined by the claims and the equivalents thereof.It is not intended that the scope of patent protection afforded thepresent invention be defined by reading into any claim a limitationfound herein that does not explicitly appear in the claim itself.

Thus, for example, any sequence(s) and/or temporal order of steps ofvarious processes or methods that are described herein are illustrativeand not restrictive. Accordingly, it should be understood that, althoughsteps of various processes or methods may be shown and described asbeing in a sequence or temporal order, the steps of any such processesor methods are not limited to being carried out in any particularsequence or order, absent an indication otherwise. Indeed, the steps insuch processes or methods generally may be carried out in variousdifferent sequences and orders while still falling within the scope ofthe present invention. Accordingly, it is intended that the scope ofpatent protection afforded the present invention is to be defined by theappended claims rather than the description set forth herein.

Additionally, it is important to note that each term used herein refersto that which the Ordinary Artisan would understand such term to meanbased on the contextual use of such term herein. To the extent that themeaning of a term used herein—as understood by the Ordinary Artisanbased on the contextual use of such term—differs in any way from anyparticular dictionary definition of such term, it is intended that themeaning of the term as understood by the Ordinary Artisan shouldprevail.

Regarding applicability of 35 U.S.C. §112, ¶6, no claim element isintended to be read in accordance with this statutory provision unlessthe explicit phrase “means for” or “step for” is actually used in suchclaim element, whereupon this statutory provision is intended to applyin the interpretation of such claim element.

Furthermore, it is important to note that, as used herein, “a” and “an”each generally denotes “at least one,” but does not exclude a pluralityunless the contextual use dictates otherwise. Thus, reference to “apicnic basket having an apple” describes “a picnic basket having atleast one apple” as well as “a picnic basket having apples.” Incontrast, reference to “a picnic basket having a single apple” describes“a picnic basket having only one apple.”

When used herein to join a list of items, “or” denotes “at least one ofthe items,” but does not exclude a plurality of items of the list. Thus,reference to “a picnic basket having cheese or crackers” describes “apicnic basket having cheese without crackers,” “a picnic basket havingcrackers without cheese,” and “a picnic basket having both cheese andcrackers.” Finally, when used herein to join a list of items, “and”denotes “all of the items of the list.” Thus, reference to “a picnicbasket having cheese and crackers” describes “a picnic basket havingcheese, wherein the picnic basket further has crackers,” as well asdescribes “a picnic basket having crackers, wherein the picnic basketfurther has cheese.”

Referring now to the drawings, in which like numerals represent likecomponents throughout the several views, one or more preferredembodiments of the present invention are next described. The followingdescription of one or more preferred embodiments is merely exemplary innature and is in no way intended to limit the invention, itsimplementations, or uses.

FIG. 1 is a front isometric view of an electronic equipment enclosureframe 12 in accordance with one or more preferred embodiments of thepresent invention, shown with a pair of vertical mounting rails 230installed thereon. As shown therein, the frame structure 12 includesfour vertical support posts 16, upper and lower front cross members17,18, upper and lower rear cross members 19,20 and three pairs of sidecross members 21,22,23. Each vertical support post 16 includes aplurality of cross member attachment apertures at each end. Two of thevertical support posts 16 are connected together at their upper andlower ends by the upper and lower front cross members 17,18,respectively, and the other two support posts 16 are connected togetherat their upper and lower ends by the upper and lower rear cross members19,20, respectively. The front cross members 17,18 and their respectivesupport posts 16 thus define a front frame (sometimes referred to as adoor threshold frame) 24, and the rear cross members 19,20 and theirrespective support posts 16 define a rear door threshold frame 26. Thefront and rear frames 24,26 may then be connected together at theirrespective corners by the upper, middle and lower side cross members21,22,23.

Although not specifically identified in FIG. 1, each upper and lowercross member 17,19 and 18,20 includes a plurality of tabs or gussets,adapted to interact with a respective end of a vertical support post 16,extending therefrom, and these tabs may be plug welded to the verticalsupport posts 16. Such an arrangement may be disclosed, for example, inco-pending, commonly-assigned non-provisional patent application Ser.No. 13/229,704, entitled, “ELECTRONIC EQUIPMENT CABINET STRUCTURE” (the“'704 Application”). Furthermore, the lower corners of each frame 24,26may be reinforced and supported by caster plates which in turn aresupported by casters. Such an arrangement may also be disclosed, forexample, in the '704 Application.

Although the particular frame structure 12 described and illustratedherein includes various novel aspects, it will be apparent to theOrdinary Artisan that some aspects of the present invention are likewiseapplicable to frame structures having one or more elements of generallyconventional design and construction. Furthermore, in some embodiments,other frame elements may be used, other connection means may be used tojoin the various members together, or both. In this regard, otherexamples of conventional connection means are described incommonly-assigned U.S. Pat. No. 6,185,098, U.S. Pat. No. 7,119,282, U.S.Pat. No. 7,697,285, U.S. Patent Application Publication No. US2009/0190307 A1, U.S. Patent Application Publication No. US 2009/0227197A1, U.S. Patent Application Publication No. US 2009/0283488 A1, and U.S.Patent Application Publication No. US 2010/0172092 A1, the entirety ofeach of which is incorporated herein by reference. Although likewise notillustrated herein, the precision and the stability of each of thecorners of at least some types of four post frame structures may beenhanced by utilizing a self-squaring corner attachment bracket such asthat disclosed by commonly-assigned U.S. Pat. No. 5,997,117, entitled“RACK FRAME CABINET,” the entirety of which is hereby incorporated byreference.

The frame structure 12 may be enclosed by one or more panels to form anelectronic equipment enclosure 10. FIG. 2 is an isometric view of aframe structure 12 of similar construction to that of FIG. 1, but ofgreater depth, shown with panels installed thereon. As shown therein,the enclosure 10 may include right and/or left panels 13, a front panel14, and a rear panel 15, one or more of which may be configured tooperate as a door to the interior of the enclosure 10 (not illustrated).Various different connection means may be used to join the variouspanels 13,14,15 to the frame structure 12. One or more novel connectionmeans may be described and/or illustrated herein. However, although notillustrated herein, it will be apparent to the Ordinary Artisan that inat least some embodiments, any of a variety of other connection meansmay be used instead to join the panels to the frame structure 12.

The enclosure 10 further includes a generally flat top panel 30 sizedand shaped to fit an opening 28 defined by the four vertical supportposts 16 in connection with the upper front cross member 17, the upperrear cross member 19, and the upper side cross members 21. Wheninstalled, the top panel 30 covers the opening 28. In a contemplatedembodiment, the top panel 30 is manufactured from sheet metal or othermetal-based material. The top panel 30 may include features such asthose described in co-pending, commonly-assigned non-provisional patentapplication Ser. No. 13/229,705, entitled, “CABLE PASS-THROUGH PANEL FORELECTRONIC EQUIPMENT ENCLOSURE” (the “'705 Application”).

In a contemplated embodiment, the upper front and rear cross members17,19 each include two spring pins 56 and a retaining flange 51 as seen,for example, in FIG. 1. As described in the '705 Application, the springpins 56 and end flanges 51 may be utilized to facilitate reversible,tool-free installation of the top panel 30.

As shown in FIG. 1, the frame structure 12 further includes one or morevertical mounting rails 230 that extend therein in a generally verticalorientation. Each vertical mounting rail 230 typically has a series ofholes 232 formed therein to facilitate easy mounting of a wide varietyof equipment to the frame structure 12. As will be explained in greaterdetail, one or more mounting clamps 240 may be used to facilitateattachment of the vertical mounting rail 230 to the frame structure 12.Other examples of frame structures with vertical mounting rails aredescribed in commonly-assigned U.S. Pat. No. 5,997,117, U.S. Pat. No.7,839,635, U.S. Pat. No. 7,804,685, U.S. Patent Application PublicationNo. US 2009/0227197 A1, and U.S. Patent Application Publication No. US2011/0148261 A1, the entirety of each of which is incorporated herein byreference. It will be appreciated that, in various embodiments, and asillustrated in the above-referenced patents and patent applicationpublications and elsewhere, vertical mounting rails may be supported bythe side cross members of the frame, by separate side horizontal railsthat are not part of the primary frame structure, or by other meansentirely.

FIG. 3 is an isometric view of one of the vertical mounting rails 230 ofFIG. 1, and FIG. 4 is a top cross-sectional view of a portion of theframe structure 12 of FIG. 1, taken along line 4-4, showing theconnection of one of the mounting rails 230 to one of the side crossmembers 21. The mounting rail 230 in FIG. 3 is shown in the sameorientation as that of the rightmost mounting rail 230 of FIG. 1. Asshown therein, the vertical mounting rail 230 is an elongate structurewhose cross-section generally includes a C-shaped portion 234, a firstsupport portion 233 extending from one end of the C-shaped portion 234,a second support portion 235 extending perpendicularly from the firstsupport portion 233, and a third support portion 237 extendingperpendicularly from the second support portion 235.

Each vertical mounting rail 230 may be fastened to the cabinet structure12 using one or more clamps 240. In this regard, the mounting clamp 240includes a clamping bracket 242 and a clamp nut 244, and the rail 230includes a plurality of embossed portions 254 for interfacing with theclamp 240. Extending at opposite lateral edges of the clamping bracket242 are flanges 246,247. The flanges 246,247 of the clamping bracket 242straddle the C-shaped portion 234 of the vertical mounting rail 230, andthe clamp nut 244 may be aligned with the embossed portion 254 of thevertical mounting rail 230, which itself is aligned with a raisedcentral portion of the clamping bracket 242. These features, and a clamp240 suitable for use in one or more preferred embodiments of the presentinvention, are described and illustrated in co-pending,commonly-assigned non-provisional patent application Ser. No.13/229,707, entitled, “RAIL MOUNTING CLAMP FOR ELECTRONIC EQUIPMENTENCLOSURE.” However, it will be apparent that in at least someembodiments, alternative side cross member structures, connection means,or both may be utilized to connect the vertical mounting rails 230 tothe frame structure 12.

A variety of mounting features is disposed along each of the first,second and third support portions 233,235,237; such features may be usedfor mounting equipment as well as cable management structures. In thisregard, FIG. 5 is an isometric view of the frame structure 12 of FIG. 1,shown with a plurality of D-rings 260 mounted on each vertical mountingrail 230, and FIG. 6 is an enlarged fragmentary isometric view of thetop right corner of the frame structure 12 of FIG. 5. With particularreference to FIGS. 3, 5 and 6, the first support portion 233 includestwo types of openings 252,253, arranged in sets. In each set are twokeyhole apertures 252 disposed above a single horizontal slot 253. Thesecond support portion 235 also includes two types of openings 255,257;circular openings 255 are arranged in a column and evenly-spaced alongthe length of the rail 230, and vertical slots 257 are arranged in pairsthat are likewise evenly-spaced, though at greater spacings, along therail 230. Finally, the third support portion 237 includes the equipmentmounting holes 232 mentioned previously. These holes are preferablysquare, but may alternatively be round, and are arranged in aconventional, standardized repeating pattern having intervals (oncenter) of ⅝″-⅝″-½″ totaling a standard rack mounting unit (“RMU”) of1.75″. The third support portion 237 thus serves as an equipmentmounting rail, suitable for use in like manner to conventional equipmentmounting rails having conventionally-spaced mounting apertures likethose shown and described herein.

In FIGS. 5 and 6, the cable management structures that are mounted onthe vertical mounting rails are D-rings 260, although a wide variety ofdifferent cable management structures may be mounted to the verticalmounting rails, as will be explained in further detail below. FIG. 7 isan enlarged fragmentary orthogonal view of one of the D-rings 260 ofFIG. 5 shown detached from the vertical mounting rail 230. Each D-ring260 includes a ring portion 261 and a support portion. The ring portion261 may be generally similar in construction to, for example, cablerings described and illustrated in commonly-assigned U.S. Pat. No.6,504,100, entitled “FLEXIBLE INTRA-CABINET CABLE RING WIRE MANAGEMENTSYSTEM,” the entirety of which is incorporated herein by reference.However, in some embodiments, other types of cable rings may besubstituted therefor. The support portion includes three elements: afirst keyhole boss 262 extending laterally from the back of a tab 264protruding upward from the back of the ring portion 261, a secondkeyhole boss (not visible, but similar to the first keyhole boss 262)extending laterally from the back of the ring portion 261, and analignment boss 266 protruding from the end of a tab 268 extendingdownward from the back of the ring portion 261. The support portion ofthe D-ring 260 is adapted to be connected to, and supported by, one setof openings 252,253 in the vertical mounting rail 230 withoutinterfering with the use of the equipment mounting holes 232. Inparticular, the two keyhole bosses 262 are arranged to interact with thekeyhole apertures 252, of the selected set of openings 252,253, in thefirst support portion 233, and the alignment boss 266 is arranged tointeract with the horizontal slot 253 of the same set of openings252,253. This interaction may perhaps be best discerned from FIGS. 6 and7.

FIG. 8 is an isometric view of a frame structure 12 of similarconstruction to that of FIG. 1, but of greater depth and width, shownwith an alternative type of vertical mounting rail 330 installedthereon, and FIG. 9 is an isometric view of one of the vertical mountingrails 330 of FIG. 8. As will be apparent, the mounting rail 330 in FIG.9 is shown in the same orientation as that of the rightmost mountingrail 330 of FIG. 1. Still further, FIG. 10 is an enlarged fragmentaryisometric view of the top left corner of the frame structure 12 of FIG.8.

The alternative mounting rail 330 of FIGS. 8-10 shares many similaritieswith the mounting rail 230 of FIGS. 1 and 3. The alternative verticalmounting rail 330 is an elongate structure whose cross-section generallyincludes a C-shaped portion 234, a first support portion 333 extendingfrom one end of the C-shaped portion, a second support portion 335extending perpendicularly from the first support portion 333, and athird support portion 237 extending perpendicularly from the secondsupport portion 335. The rail 330 may be fastened to the cabinetstructure 12 using one or more clamps 240 in similar fashion to that ofFIG. 3. A variety of mounting features is disposed along each of thefirst, second and third support portions 333,335,237; such features maybe used for mounting equipment as well as cable management structures.The first support portion 333 includes at least two types of openings252,253, arranged in sets. In each set are two pairs of keyholeapertures 252 disposed above a single horizontal slot 253, which iscentered therebetween. The second support portion 335 includes circularopenings 255 are arranged in a column and evenly-spaced along the lengthof the rail 330. The third support portion 237 includes the standardizedequipment mounting holes 232 mentioned previously. In addition to otheropenings, one or more of the support portions 333,335,237 may be adaptedto facilitate routing of cables from one side of the frame structure 12to the other. Options and features for accommodating cable pass-throughat a vertical mounting rail may be disclosed, for example, inco-pending, commonly-assigned non-provisional patent application Ser.No. 13/229,706, entitled, “RAIL SEAL FOR ELECTRONIC EQUIPMENT ENCLOSURE”(the “'706 Application”).

In FIGS. 8 and 10, the cable management structures that are mounted onthe vertical mounting rails are D-rings 360, although a wide variety ofdifferent cable management structures may be mounted to the verticalmounting rails, as will be explained in further detail below. FIGS. 11and 12 are enlarged fragmentary orthogonal view of the left side andrear of one of the D-rings 360 of FIG. 8 shown detached from thevertical mounting rail 330. Each D-ring 360 includes a ring portion 361and a support portion. The ring portion 361 may be generally similar inconstruction to the ring portion of the D-rings of FIGS. 5-7 andvariations thereof. The support portion includes five elements: fourkeyhole bosses 362 extending laterally from the back of the ring portion361, and an alignment boss 266 protruding from the end of a tab 368extending downward from a central area of the back of the ring portion361. The support portion of the D-ring 360 is adapted to be connectedto, and supported by, one set of openings 252,253 in the verticalmounting rail 330 without interfering with the use of the equipmentmounting holes 232. In particular, the four keyhole bosses 362 arearranged to interact with the keyhole apertures 252, of the selected setof openings 252,253, in the first support portion 333, and the alignmentboss 266 is arranged to interact with the horizontal slot 253 of thesame set of openings 252,253. This interaction may perhaps be bestdiscerned from FIGS. 10-12 but is somewhat similar to that of theD-rings 260 shown in FIGS. 6 and 7.

Notably, the D-rings 260,360 described and illustrated herein may beconnected to, or mounted on, the vertical mounting rails 230,330 withoutthe use of tools. In particular, the D-rings 260,360 may be mounted byinserting the keyhole bosses 262,362 into the upper (wider) portion ofrespective keyhole apertures 252 and lowering them until they are seatedin the lower (narrower) portion thereof, at which point the alignmentboss 266 snaps into place in the horizontal slot 253. In at least someembodiments, keyhole apertures 252 may be of varying sizes. For example,in at least some embodiments, an upper keyhole aperture may be smallerthan a lower keyhole aperture.
